Study of Brazilian commercial Oriented Strand Board panels using stress wave
(2013-08-09)
Today lumber industry has shown a clearly evident trend towards wood based panels' production; and, among them, Oriented Strand Board (OSB) has become more and more prominent. Nondestructive Testing (NDT) such as stress ...
Falling sheet envelope method for non-destructive testing time-dependent signals
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
In this work, an algorithm to compute the envelope of non-destructive testing (NDT) signals is proposed. This method allows increasing the speed and reducing the memory in extensive data processing. Also, this procedure ...
Sparse arrays and image compounding techniques for non-destructive testing using guided acoustic waves
(2013-06-01)
Piezoelectric array transducers applications are becoming usual in the ultrasonic non-destructive testing area. However, the number of elements can increase the system complexity, due to the necessity of multichannel ...

Hybridization effect on the mechanical properties of curaua/glass fiber composites
(2013-08-20)
The aim of this paper was to evaluate the effect of hybridizing glass and curaua fibers on the mechanical properties of their composites. These composites were produced by hot compression molding, with distinct overall ...
Hinkley criterion applied to detection and location of burn in grinding process
(2021-04-01)
Grinding is a machining process widely applied in the manufacture of products that require low tolerance and high-dimensional accuracy. One of the most critical issues in this manufacturing process is the material burn ...
Avaliação da distribuição da densidade em MDF a partir da técnica da onda de ultra-som
(2007-06-01)
The goal of this research was to determine the density distribution in medium density fiberboard (MDF), manufactured with polyurethane derived from castor oil using, ultrasonic wave technique. The equipment used in this ...
